RF Power Detector
General Description
The MAX2204 RF power detector is designed to oper-
ate from 450MHz to 2.5GHz. The device is ideal for
wideband code-division multiple access (WCDMA),
cdma2000®, and high-speed downlink/uplink packet
access. The MAX2204 accepts an RF signal at the
input, and outputs a highly repeatable voltage. The out-
put voltage increases monotonically with increasing
input power. The device is designed to compensate for
temperature and process shifts, reducing the typical
output variation to less than ±0.5dB at full input power
and ±1.5dB at the lower power.
The MAX2204 features a detection range from -16dBm
to +5dBm. High input impedance allows for low-loss
resistive tap if an isolator is used. The device uses
external termination at the input so that the RF signal
from several directional couplers can be connected to
a single detector chip.
The MAX2204 operates from a 2.7V to 3.3V power
supply. The device is available in a tiny 5-pin SC70 pack-
age. Electrical performance is guaranteed over a -40°C to
+85°C temperature range.

Layout
The MAX2204 is not particularly sensitive to the layout,
since it only needs 5dBm for maximum output voltage.
However, there are two areas that need attention: the
GND pin and the supply bypassing. The GND pin should
be connected to the PCB ground with a GND via as
close as possible, and the supply bypass capacitor
should be close to the part.
Figure 2. Typical Application Circuit Using Resistive Tapping
from a Power Amplifier
The MAX2204 has high input impedance to allow
for high-value resistive tapping from a power amplifier.
This coupling method is the lowest cost and lowest
power loss when used with an isolator. See Figure 2 for
the typical application circuit.
The MAX2204 input impedance over frequency is listed
in Table 1.
